At least 25 people were killed Thursday by a car bomb targeting a market north east of the Iraqi capital Baghdad, local media reported.
The bombing in the town of Saadiya injured at least 30, reported the independent broadcaster Al-Sumaria TV, citing a local official.
The attack comes a day after a series of car bombings in Baghdad left at least 20 dead, dpa reported.
There has been a sharp rise in attacks in Iraq in recent months, targeting crowded places including markets, coffee shops and mosques.
The surge has raised fears of a return to the violence that pushed the country to the brink of civil war in 2006 and 2007.
According to UN estimates, 979 people were killed in attacks in October alone.
